Where did you add this exactly?

If the files are under package/ then do_install is already working fine, so your 
hack definitely isn't going to help.

When I have problems like this I generally follow this procedure to find the 
issue:

1) Is do_install working? (check "image" subdirectory under the workdir for 
the recipe, which is ${D})

2) Has do_package put the file in the package you think it should be in? (look 
in "packages-split" under the workdir for the recipe; there are subdirectories 
for each package created by the recipe)

3) Is the package really being installed? (check bitbake -e imagename and look 
at the IMAGE_INSTALL value to see if it's really in there, and also look at 
log.do_rootfs for the image - is the package mentioned?)

Cheers,
Paul
